About our construction mastic in Gelston
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list. Our aim is joints that pass at the first inspection, area by area through the programme. We work on sanitary and kitchen joints, window and door perimeters and internal decorators’ caulk, and the usual reasons a site gets in touch are old sealant on a refurbishment that needs stripping before new work and early adhesion failures on new external joints. Whoever orders the work in Gelston, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
External sealing around Gelston depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

What else we do in Gelston
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Specifying the product where the designer hasn’t
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.

Questions about Gelston
Can you work to our programme on a site in or near Gelston?
Yes. The mastic is planned around your key stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Gelston too small for you to travel to?
No. Small places get the same service as large ones. We cover the whole of Scotland. Good photographs up front let us bring everything on the first visit.
What guarantee comes with a mastic package?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
Can you come in just for snagging?
Yes. Snag-only work is something we take on.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Signs you need construction mastic in Gelston
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
These are often picked up first by site or facilities staff:
- Internal caulk splitting as the building dries out
- Bath and shower joints scraped during the final clean
- External joints sealed in damp or cold conditions that are now failing
- Missed perimeter joints on a new elevation
On any site in or around Gelston, the mastic follows the specification and the programme.

Advice
How the quote is worked out
These are the things that shape the price:
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- Which sealant the job calls for
- Site requirements such as inductions and permits
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
However big the job, the same details help:
- A wide shot and a close-up of the area
- The product your specification calls for
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
For a fixed quote, call the office on 01277 525 020 or email a schedule or drawings. You can also send details through our quote form.
